Issues with Phantom Power on Xenyx 1204USB

Hello, I have a Xenyx 1204USB and I have been using Sennheiser e935 balanced and dynamic mics. When I have had to turn on phantom power for a guitar pedal, it causes the audio quality in the mics to go flat and lose depth, and also go unreponsive to any controls. I was under the understanding that phantom power would not affect balanced mics, but since the phantom power is global to the unit, I cannot operate without it causing the issue with the mics. Has anyone had this issue before?

@BrianLowe and @remedyroom, check the cable wiring (pin 1 to pin 1, etc.). Phantom is applied to pins 2 and 3 and referenced to ground (see here). If wiring is not correct, it could cause issues.
